"This update for ghostscript fixes several issues. These security
issues were fixed :

  - CVE-2017-9835: The gs_alloc_ref_array function allowed
    remote attackers to cause a denial of service
    (heap-based buffer overflow and application crash) or
    possibly have unspecified other impact via a crafted
    PostScript document (bsc#1050879).

  - CVE-2017-9216: Prevent NULL pointer dereference in the
    jbig2_huffman_get function in jbig2_huffman.c which
    allowed for DoS (bsc#1040643).

  - CVE-2016-10317: The fill_threshhold_buffer function in
    base/gxht_thresh.c allowed remote attackers to cause a
    denial of service (heap-based buffer overflow and
    application crash) or possibly have unspecified other
    impact via a crafted PostScript document (bsc#1032230).

  - CVE-2017-9612: The Ins_IP function in base/ttinterp.c
    allowed remote attackers to cause a denial of service
    (use-after-free and application crash) or possibly have
    unspecified other impact via a crafted document
    (bsc#1050891).

  - CVE-2017-9726: The Ins_MDRP function in base/ttinterp.c
    allowed remote attackers to cause a denial of service
    (heap-based buffer over-read and application crash) or
    possibly have unspecified other impact via a crafted
    document (bsc#1050889).

  - CVE-2017-9727: The gx_ttfReader__Read function in
    base/gxttfb.c allowed remote attackers to cause a denial
    of service (heap-based buffer over-read and application
    crash) or possibly have unspecified other impact via a
    crafted document (bsc#1050888).

  - CVE-2017-9739: The Ins_JMPR function in base/ttinterp.c
    allowed remote attackers to cause a denial of service
    (heap-based buffer over-read and application crash) or
    possibly have unspecified other impact via a crafted
    document (bsc#1050887).

  - CVE-2017-11714: psi/ztoken.c mishandled references to
    the scanner state structure, which allowed remote
    attackers to cause a denial of service (application
    crash) or possibly have unspecified other impact via a
    crafted PostScript document, related to an out-of-bounds
    read in the igc_reloc_struct_ptr function in psi/igc.c
    (bsc#1051184).

  - CVE-2016-10219: The intersect function in base/gxfill.c
    allowed remote attackers to cause a denial of service
    (divide-by-zero error and application crash) via a
    crafted file (bsc#1032138).
